Faulty Undersea Cable Triggers Islandwide Blackout on Bornholm

Engineers are starting the Rønne power plant, with electricity expected to return around 9 p.m.

Overview

  • Power failed at 10:16 a.m. after the SwedenBornholm link went down, the local operator Trefor said.
  • Approximately 18,572 households lost electricity, and Trefor warned of possible interruptions to water, heating and communications.
  • State grid operator Energinet reported zero megawatts flowing through the undersea cable on Wednesday morning.
  • Trefor is working to restore supply locally by running the Rønne plant, with service provisionally targeted for this evening.
  • Bornholm police opened an investigation as the island’s reliance on a single submarine connection draws comparisons to past Baltic infrastructure damage, including a 2022 anchor strike.
